Unselfish Blues skipper sweats on calf injury

BLUES captain Boyd Cordner promises not to play in next week's Origin decider if his calf injury isn't right.

Cordner injured his calf in the Origin II loss to Queensland at ANZ Stadium and has not played since.

"It's only been (12 days) since game two," he said.

"It's improving day by day and we've still got a lot of time between now and kick-off."

The Sydney Roosters back-rower will give himself until the team's last major training run on Sunday to complete a full session with the team, but he maintains he won't play unless he's confident he can last the full 80 minutes.

"I won't be that selfish," he said.

"I'm not that stupid. I don't want to put the team in a position where if I can't finish the game or it happens early then we're down an interchange.

"I definitely won't be putting myself before the team at all. I want what's best for the team."

Cordner is joined under the injury cloud by lock Tyson Frizell (ribs and back), and backs James Tedesco and Josh Dugan (leg problems).

The 25-year-old said it took him days to smile again after the Blues surrendered a 10-point lead to the Maroons in game two.
